ICD-10 Code J12.8 – Other Viral Pneumonia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J12.8 – Other viral pneumonia
What it is
J12.8 identifies pneumonia caused by a viral agent not specifically named elsewhere in the classification. Use it when the record states viral pneumonia but does not name a more specific virus.
Clinical signs
Typical findings include cough, fever, shortness of breath, and chest imaging consistent with pneumonia. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents viral pneumonia and the causative virus is not identified or is listed as another specified virus. It may also fit cases where the chart confirms viral pneumonia but does not support a more specific code. Check documentation for organism details and sequencing instructions.
Do not use for
Do not use J12.8 for bacterial pneumonia, aspiration pneumonia, or pneumonia with a clearly identified virus that has its own ICD-10-CM code. Check documentation if the organism is named elsewhere.
Coding tip
Look for the specific viral organism in the assessment, lab results, or discharge summary before assigning J12.8.
